Abstract: A display system includes a rendering device and a display device. The rendering device is to render a sequence of frames for display at the display device, wherein the display device is to use an illumination strobe during each frame period associated with a corresponding frame of the sequence of frames. The rendering device further is to determine a position of the illumination strobe within each frame period based one or more input parameters, each input parameter representing a corresponding operational characteristic of one of the rendering device or the display device.

Abstract: Briefly, methods and apparatus to provide image content to, and display image content on, variable refresh rate displays with reduced input lag. The methods and apparatus allow for image tearing, or the displaying of image content from more than one video frame, when the render rate of a provided video frame falls outside the display refresh rate range of a variable refresh rate display when the display is refreshing with a previous frame (e.g. the display is in active refresh), thus reducing the input lag of the content of the provided video frame. The methods and apparatus may also prevent image tearing when the render rate of provided video frames is within the display refresh rate range of a display.

Abstract: A display system includes a rendering device and a display device. The rendering device is to render a sequence of frames for display at a frame rate and to set an illumination configuration to be applied by the display device during a frame period for each frame of the sequence of frames based on the frame rate. The illumination configuration controls at least one of an illumination level and a duration for an illumination strobe, and at least one of an illumination level for an illumination fill preceding the illumination strobe in the frame period and an illumination level for an illumination fill following the illumination strobe in the frame period. The display device is to receive a representation of the illumination configuration from the rendering device and apply the illumination configuration during a frame period for each frame of the sequence of frames to display the frame.

Abstract: A single source image encoder encodes more than one display stream, such as multiple display streams each for a different display or multiple display streams for the same display, using multiple indexed color history (ICH) buffers. As applied to a DSC encoder, the same DSC encoder is used to encode more than one DSC compliant display stream. Multiple encoded display bitstreams are output as multiple display data streams to a plurality of displays. Such a configuration can significantly reduce the area cost of an integrated circuit that employs an image encoder since additional encoders are eliminated.

Abstract: A three-dimensional (3-D) look up table (LUT) can be accessed using an address decoder to identify a plurality of vertices in the 3-D LUT based on a number (m) of most significant bits (MSBs) of three coordinate values representative of a first color and a non-zero integer (p). The three coordinate values are determined by a source gamut. One or more memories store component values representative of a plurality of second colors determined by a destination gamut. The component values are stored at memory locations associated with the plurality of vertices. An interpolator maps the input color to an output color in the destination gamut based on the component values.

Abstract: A display system includes a rendering device and a display device having a plurality of individually-controllable illumination regions. The rendering device is to render a frame for display at the display device during a frame period and to determine a brightness representation for each region of a plurality of regions of the frame, each region of the frame corresponding to an illumination region of the display device. The rendering device further is to set, for each illumination region, an illumination configuration to be applied by the display device for the illumination region during at least one of the frame period and a subsequent frame period based on the brightness representation for the corresponding region of the frame, wherein the illumination configuration controls at least one of an illumination level, a duration, and a position of an illumination strobe to be implemented for the corresponding illumination region.
